Any uses for Windows Live writer?

Just curious but is anyone out there using the Windows Live writer for anything? I noticed Jeff tested it the other day. I have to admit that I installed and tested it way back and since then have not really found any useful reason to go back and use it again. I have to admit that my PC was getting really bogged down and running like a gutless pig so during my weekly clean-up, defrag, yadayada I removed all the malware, crapware, spyware and whathave you... on the list of things that went included the Live writer app. I guess if I was an avid user of "Spaces" I'd likely find it a bit more useful - see http://windowslivewriter.spaces.live.com/ for more on this topic.
